CITY OF HOUSTON RFP S29- T22459 EARLY RELEASE COVERAGE REQUIREMENTS, 4/23/07

Section 700/800 MHz Trunked Radio & Communications 1 System Coverage Performance

1.1 Overview of Required Coverage

Reliable two-way radio coverage is the foundation of any Public Safety and Local Government radio communications system. The City of Houston has outgrown its current Police, Fire / EMS, and Public Works & Engineering radio systems and is in the process of replacing these systems. The new radio system developed through this project will represent a new start, a new system, and a new era in wireless communications for the City of Houston.

The purpose of this section in the RFP is to clearly articulate the City’s preliminary radio coverage requirements for the new system so that proposers can develop their system offerings with a clear understanding of the City’s expectations and requirements. There are many aspects of radio coverage performance that will be addressed in this Section of the RFP so that proposers can have relevant, factual information upon which to develop their system designs. It is important to note that the information that follows is preliminary and is subject to change prior to release of the finalized system RFP. The City will not be responsible for any costs involved in the vendors’ proposal development.

The enclosed information is being released early, prior to the release of the full system RFP in an effort to provide qualified responders preliminary information so that they can begin the process of developing their system strategies. Hopefully, this early information will help reduce the time needed for the preparation of system proposals after the final RFP document is released by the City.

Some of the topics contained in this early release include:

¾ A description of the City’s required coverage areas

¾ The type of coverage required i.e. mobile, portable on street, portable in light structures, portable in medium / heavy structures, and coverage in special areas such as the City’s downtown tunnel system and selected buildings

¾ Use of portable radios (head level / belt level, speaker mics, radio carrying devices such as swivel attachments for belt use)

¾ Delivered audio quality performance (TIA / TSB-88 DAQ – voice sound quality required for the system)

¾ Coverage reliability throughout the defined coverage areas

¾ A brief overview of coverage acceptance testing requirements that will be used to verify coverage performance once the system has been constructed

Each of these issues is addressed in detail in the following pages of this Section.

The City of Houston understands that one of the more challenging aspects of system development involves site selection and the number of sites needed for use in developing a system configuration. Any new system implemented by the City must comply with FCC regulatory requirements, including spectral efficiency. It is important that the system proposed for this project be capable of meeting radio coverage and spectral efficiency requirements without having to add a significant number of additional repeater sites after the initial purchase.

To assist vendors in system development, several helpful pieces of information will be included in this Section of the RFP.

This information includes the following:

¾ A listing of existing City radio tower locations

¾ A listing of City water towers

¾ A listing of City properties that may potentially support the development of new additional tower sites needed to meet coverage requirements

¾ A detailed listing of required buildings in which coverage is mandatory including a supplemental map of the Houston area with the buildings plotted on the map.

¾ A map of the Downtown underground tunnel system which must be covered

1.1.1 Coverage Definition

Coverage is defined as the ability to successfully complete inbound (field to dispatch) outbound, (dispatch to field), and radio to radio voice communications in a repeat mode via the system infrastructure throughout the designated areas, standing still, and while in motion, with at least the minimum required level of audio quality (per TIA / TSB-88B or latest approved version DAQ) and with at least the specified level of propagation reliability stated in this Section. This level of performance is required for analog (if proposed), digital, and digitally encrypted modes of operation.

Audio Quality

For informational purposes, proposers will be required to submit with their proposals their recorded samples of analog and digital voice messages for the following DAQ levels:

♦ DAQ 2.0 ♦ DAQ 3.0 ♦ DAQ 3.4 ♦ DAQ 4.0 ♦ DAQ 5.0

Audio samples may be submitted in the .WAV file format on CD-R media and will be reviewed by the City’s evaluation team. For reference, the DAQ definitions, as defined in Bulletin TSB-88 are listed below:

Table 1 – Delivered Audio Quality Scale Definitions

700/800 MHZ TRUNKED RADIO & COMMUNICATION SYSTEM PAGE 2 CITY OF HOUSTON RFP S29- T22459 EARLY RELEASE COVERAGE REQUIREMENTS, 4/23/07

Delivered Audio Quality Subjective Performance Description DAQ 5.0 Speech easily understood. DAQ 4.5 Speech easily understood. Infrequent Noise/Distortion. DAQ 4.0 Speech easily understood. Occasional Noise/Distortion. DAQ 3.4 Speech understandable with repetition only rarely required. Some Noise/Distortion. DAQ 3.0 Speech understandable with slight effort. Occasional repetition required due to Noise/Distortion. DAQ 2.0 Understandable with considerable effort. Frequent repetition due to Noise/Distortion. DAQ 1.0 Unusable, speech present but unreadable.

Coverage Reliability All references to coverage reliability in this document refer to area reliability. For example, the phrase "95% coverage" indicates that 95% of the bounded areas described shall exhibit the specified coverage resulting in a DAQ 3.4 at least 95% of the time. It will not be acceptable to provide a design where two or more adjacent failed grids exist, that is, failed points shall not be unique to any one vicinity, while still meeting the overall coverage reliability goals.

1.1.2 Mobile Radio Coverage

Mobile radio coverage will likely be limited by the Region 51 700 MHz plan guidelines which are undergoing finalization at this time. Mobile coverage performance will be expected to exceed and extend beyond the range of portable radios. Additional information regarding mobile coverage will be provided in the final system RFP.

The Houston Police Department currently utilizes low silhouette “blade type” radio antennas mounted on the trunk lid of its police vehicles. HPD wants to continue this practice; therefore the antennas for the HPD units shall be of this type.

Portable Radio Coverage On-Street Portable radio coverage on-street shall be provided with the portable radio and antenna worn on the waist (3’ AGL) throughout the designated areas in Figure 1 that follows. For day-to-day operation, some user agencies may use speaker/microphones with antennas, however for system design, radio coverage prediction, proposal development and system acceptance testing, speaker/ microphones with antennas on the mic shall not be used. The radio will be positioned at belt level with the antenna. Unusually large portable radio antennas may present operational problems for some user personnel. Proposers must clearly identify the specific antenna proposed for this project and must provide sample radios with the proposed antenna at their oral presentation after submission of a system proposal. Other portable radio antennas that are not proposed shall not be shown at the oral presentations.

Some vendors state that their portable radio carrying devices impact coverage performance. To eliminate ambiguity in this area, the City is requiring that the system design be based on a “belt clip” carrying device. If the carrying devices for your portable radio (leather case with swivel attachment, etc.) have an impact on coverage performance, such impact shall be clearly described in the section of your proposal that includes your proposed coverage maps. It is important that the system design be based on real-world operational characteristics and a “worst case” carrying device which will be defined as the belt clip device.

700/800 MHZ TRUNKED RADIO & COMMUNICATION SYSTEM PAGE 5 CITY OF HOUSTON RFP S29- T22459 EARLY RELEASE COVERAGE REQUIREMENTS, 4/23/07

In-Building Coverage – 10 dB Structures (Typically residential structures) Coverage is required for portable radios worn on the belt within residential or other structures, defined as buildings with 10 dB or less penetration loss, within the area depicted in Figure No. 1 on the previous page.

In-Building Coverage – 20 dB Structures (Typically medium to heavy structures) A system infrastructure baseline of 20 dB in-building coverage is required for portable radios worn on the belt while operating within structures having up to 20 dB of penetration loss within the areas depicted in Figure No. 1 on the previous page.

Downtown Area In-Building Coverage – 30 dB Structures (Typically heavy structures) A system infrastructure baseline of 30 dB in-building coverage is required for portable radios worn on the belt while operating within the bounded downtown area depicted in Figure No. 2 that follows. Heavier coverage is required in this area due to the type and nature of structures in the downtown area.

Downtown Tunnel System Portable radio coverage is required throughout the tunnel system and in the accompanying underground business locations that are directly attached to or at the intersections of tunnels.

The listing of buildings is substantial. The City prefers that in-building coverage be provided directly by the radio infrastructure. The City also recognizes that even with a baseline system providing 20 dB of in-building coverage, (30 dB in the downtown area) there will still be some buildings within the City that have much greater penetration loss. Additional measures may be required to facilitate coverage in those facilities. To extend coverage beyond the 20 and 30 dB levels, the City will consider secondary methods of providing heavier coverage within such structures. Such methods might include: • Increasing the baseline coverage of the infrastructure in a particular area of the City to support higher levels of building penetration as was done in the immediate downtown area.

• Installation of multi-band channelized bi-directional amplifier systems in selected buildings where building access is permitted. Costs for such solutions shall be provided on a case by case basis so that the City can utilize available funding in a manner that best meets the City’s needs.

• Installation of a fiber optic based in-building RF distribution system

• Utilization of vehicular repeater systems or other similar systems to extend tactical on-scene radio coverage into heavy structures

Hi-rise buildings present significant communication problems for the Police and Fire Departments when working events inside such facilities, particularly when trying to communicate between the lower floors and upper floors of the facility. It is the intent of the City to resolve such problems to the extent feasible as part of this project. Downtown Underground Tunnel System The City of Houston downtown tunnel system consists of a number of underground walkways that allow people to travel throughout many parts of the downtown area under the streets and from building to building. The system consists of the following tunnels:

• Main Tunnel Loop (One Shell Plaza) • S. Louisiana Tunnel • W. Dallas Tunnel • W. Walker Tunnel • N. Louisiana Tunnel • N. Travis Tunnel

700/800 MHZ TRUNKED RADIO & COMMUNICATION SYSTEM PAGE 11 CITY OF HOUSTON RFP S29- T22459 EARLY RELEASE COVERAGE REQUIREMENTS, 4/23/07

• E. McKinney Tunnel • Harris County Tunnel

All of the tunnels are interconnected with the exception of the Harris County Tunnel.

The 6-mile network of tunnels connects most major buildings. Originally designed for individual businesses, the tunnels were extended bit by bit to connect over 82 buildings. Now more than 100 shops, restaurants, cafes and galleries have been built into the tunnel system. The tunnels themselves are generally narrow (10-15 ft) walkways, as seen in Figure 3, that open into larger areas where shops and restaurants or food courts are located (Figure 4).

1.5 Radio Coverage Prediction

For the purposes of your proposal, radio system coverage shall be predicted through the use of a radio wave propagation model which has been developed on the basis of theoretical and empirical data, and which will take into account channel bandwidth, modulation schemes, delivered audio quality, coverage reliability, terrain irregularity, foliage, land use / land cover, building penetration losses, noise, and long- and short- term signal variations. The model used for the purposes of the coverage prediction process shall be identified in your proposal, and the rationale for system gains and losses used must be provided in your proposal. A table of system coverage parameters such as gains and losses utilized in each propagation analysis must be provided. A terrain database with a minimum of 3 arc-seconds of resolution is required. You must identify the terrain data model used in your coverage predictions. Your propagation analysis system must utilize both vertical and horizontal antenna patterns.

Coverage maps for individual site analyses shall be presented on 11" x 17" media using a USGS 1:250,000 scale topographical maps. The scale on the finished map shall be 1” = 4 miles. Each coverage analysis shall include a legend with the following information:

¾ Type of coverage displayed on the map, mobile, portable on-street, portable in 10 dB buildings, portable in 20 dB buildings, portable in 30 dB buildings.

¾ Location of portable radio (radio and antenna at belt level – 3ft. AGL)

¾ Delivered Audio Quality (DAQ)

¾ Analog (if proposed), digital clear mode, digital encrypted mode.

¾ Radio coverage reliability shown, percent reliability and type of reliability (area vs. contour)

¾ Type of carrying device used with portable radio (belt clip)

¾ RF signal levels in dBm corresponding to the coverage colors displayed on the map

¾ Simulcast capture ratio in dB and targeted propagation delay in microseconds for simulcast sites

¾ Square mileage of each type of proposed coverage shown on the coverage analysis or on an accompanying parameter sheet

To streamline the evaluation process, the City is requiring that all vendors use the same map format as shown below:

¾ On-Street portable coverage with portable radio worn at hip level (3' AGL) using a speaker microphone without antenna (coverage shown in green)

¾ In-building portable coverage, radio worn at belt level (3' AGL):

♦ Inside standard structures, up to 10 dB penetration loss (blue)

♦ Inside heavy structures, up to 20 dB penetration loss (red)

700/800 MHZ TRUNKED RADIO & COMMUNICATION SYSTEM PAGE 15 CITY OF HOUSTON RFP S29- T22459 EARLY RELEASE COVERAGE REQUIREMENTS, 4/23/07

♦ Inside downtown area structures, up to 30 dB penetration loss (yellow)

♦ Mobile coverage, trunk mounted blade type antenna, centerline at 4’ above ground (purple)

Portable coverage maps shall be prepared for the limiting case (talkout vs. talkback). A mobile talkout coverage map shall also be provided along with the bit error threshold for DAQ performance. All RF coverage maps shall be provided to the City in both printed and electronic formats. The electronic versions shall be provided in a common GIS format for further coverage analysis by the City. The following map file formats are acceptable.

¾ ESRI shape files ¾ ESRI export files ¾ Mapinfo Mif or Mid

Land Use / Land Cover Data

A separate map exhibit must be provided showing your land use / land cover data used for this project. The source and publication date of your Land use / land cover database must be provided. The latest available data is preferred along with a color land use map showing where each use category was used. A table that describes each use category and lists the loss value associated with it shall accompany this map.

Simulcast Time Delay Interference

In the event that your proposed system configuration utilizes simulcast technology, your proposed coverage maps must account for (display) any harmful time delay interference (TDI) that may occur in your proposed system configuration. This means that forecasted areas of TDI must be clearly shown on your coverage maps or be shown as “non- covered” areas.

If you are proposing a simulcast configuration, you must identify the delay threshold in microseconds and capture ratio in dB on which the City’s system design is based.

1.6 Brief Overview of Radio Coverage Testing

Coverage testing shall be conducted as part of the System Acceptance Testing process to verify that the appropriate levels of coverage performance have been provided. The following provides a brief preliminary listing of tests that shall be performed to verify coverage performance. The final system RFP will include more complete detail regarding coverage testing.

The City of Houston will supervise the entire coverage testing process. For test purposes, with the exception of the downtown area, the City shall be divided into uniform square grids of approximately 1/2 mile by 1/2 mile in area. For better testing resolution downtown, the downtown area as shown in Figure 2 will be divided into 1/10 mile by 1/10 mile grids.

The City and vendor will test coverage in all accessible grids. Grids that are not accessible by the test teams shall not be counted in the reliability calculation. The City may elect to pass certain grids if it is obvious that they are adequately covered.

700/800 MHZ TRUNKED RADIO & COMMUNICATION SYSTEM PAGE 16 CITY OF HOUSTON RFP S29- T22459 EARLY RELEASE COVERAGE REQUIREMENTS, 4/23/07

The portable radio voice testing shall be performed using random sentences read from daily, periodicals. Both analog (if proposed) and digital (clear and encrypted) voice modes will be tested. Extrapolation of results from tests in one direction to reach conclusions about the other direction will not be acceptable. This is a two-way radio system. A failure in the inbound, outbound, or radio to radio mode, either moving or stationary at a test location, will constitute a failed test location, which will be subject to a test retry.

Test Retry

In the event that the first test call (inbound, outbound or radio to radio) is unsuccessful, the field team will be allowed to move up to 5’ and a retry will be permitted. If the second attempt to communicate fails (no access or audio quality below DAQ 3.4), that test location will be deemed a failure.

All retries will be counted. No more than 5% of the retries will be allowed to pass this portion of the coverage testing process.

Roaming Software

If your proposed system utilizes roaming software in the user radios to change sites as the user radio moves throughout the City’s service area, that software must be properly installed, calibrated, and optimized prior to radio coverage testing. If proposed by the vendor, site roaming will be an important part of day to day operation and will be factored into the coverage testing process. This means that if a radio fails to affiliate with the proper repeater site and the test calls are unsuccessful as a result, the test call fails.

Portable Radio Coverage

Portable radio coverage will be thoroughly tested. The following tests are currently planned:

¾ On-Street Voice Quality Tests throughout the specified area

¾ In-Building Voice Quality Tests

♦ Random buildings with up to 10 dB of penetration loss ♦ Random buildings with up to 20 dB of penetration loss ♦ Downtown buildings with up to 30 dB of penetration loss ♦ Downtown underground tunnel system ♦ All required buildings

Mobile Radio Coverage

¾ Outbound Signal Strength Measurement and Bit Error Rate test throughout the required areas

¾ Voice Quality Tests (stationary, and vehicle moving up to 80 MPH)
